Results of surgical treatment of cervical esophageal diverticula.

On the basis of 20 years' experience, the authors present the immediate and long-term results of operative treatment of Zenker's diverticulum. Comparison of two methods of surgery - diverticulopexia (in 21 patients) and excision (in 16), both associated with upper esophageal sphincter myotomy - shows good immediate and longterm results (from 1 to 19 years), with disappearance of symptoms (dysphagia) in all patients. There was no perioperative mortality. Postoperative complications were most commonly of pulmonary origin and were observed in a third of patients in both groups. In two patients from the group treated with excision, a leak from the suture line occurred, which healed spontaneously. These two patients had transient dysphagia in the postoperative period. On the basis of this analysis, the authors conclude that diverticulopexia is a safer surgical procedure than excision, giving less complications and a very good long-term functional result.

The development and evaluation of a new aerosol irritant assay with minimal animal stress.

Current aerosol irritant assays trap animals in noxious atmospheres and put a lot of stress on them. For this reason, the Minimal Animal Stress Irritant Assay Chamber (MASIAC) was developed based on the principle of avoidance, and evaluated. The MASIAC reproducibly detected citric acid with more sensitivity than conventionally used assays. With a group of mice tested simultaneously, the responses were not significantly affected by the presence of other mice. In addition, following multiple exposures to citric acid, the mice either sensitized to the irritant, or learned to avoid it. This suggests a number of areas where the MASIAC could be applied, including behavioral and asthma research. If this new method turns out to be as good as currently used assays, it could provide investigators with an alternative, more humane method of evaluating pulmonary irritants.

Liver transplantation in the experience of the centre commencing the program.

From 1989 to 1999, 43 orthotopic liver transplantations (OLT) in 40 patients (3 retransplantations) were performed in our Department. The most common indications for OLT were noninflammatory, primary cholestatic liver diseases and postinflammatory liver cirrhosis. Fourty OLT's were done for elective indications, three--on emergency basis, because of fulminant liver failure. The majority of transplantations was performed with classical technique with the excision of retrohepatic vena cava and routine use of the extracorporeal veno-venous bypass. Only in 4 patients the piggyback technique was used and performed without temporary portocaval anastomosis. All 3 patients transplanted for fulminant liver failure died in the perioperative period. Twenty four patients are still alive and well, the longest period of observation exceeding 5 years.

[Intrahepatic portocaval shunt as a new method for treating and prevention of bleeding from esophageal varices in portal hypertension]. / Wewnatrzwatrobowe zespolenie wrotno-systemowe jako nowa metoda w leczeniu i zapobieganiu krwotokom z zylaków przelyku w nadcisnieniu wrotnym.

UNLABELLED: The aim of this study was the presentation of percutaneous transjugular intrahepatic porto-systemic shunt (TIPS) and its place among the other methods of the treatment of esophageal variceal bleedings. In the period from June 1992 to December 1997, 31 cirrhotic patients with portal hypertension and recurrent variceal bleedings were submitted for TIPS. This group consisted of 14 female and 17 male patients, their age ranging from 17 to 68 years (average 52). According to Child-Pugh classification 4 patients represented group A, 11--group B and 16--group C. Each of these patient was admitted to our Department after recurrent bleeding, resistant to typical treatment: terlipressein infusion, balloon tamponade and endoscopic sclerotherapy. In 24 patients (78%) TIPS was performed successfully. In 7 cases TIPS was performed in candidates for orthotopic liver transplantation. CONCLUSIONS: TIPS is quite new, nearly 10 years old method for portal decompression. It is an effective and less invasive method than surgical procedures in the treatment of portal hypertension, especially in Child-Pugh group B and C patients if the sclerotherapy is not effective. It protects cirrhotic patients waiting for liver transplantation against the esophageal bleedings.

[Results of surgical treatment for Zenker's diverticula]. / Wyniki leczenia chirurgicznego uchylków Zenkera.

From 1976 to 1996, thirty nine patients were surgically treated for pharyngoesophageal diverticulum. The present study aimed to compare two methods of operative treatment of Zenker's diverticulum: excision (group I) and pexy, both of which were associated with upper esophageal sphincter myotomy. The main indication for surgery was dysphagia. The diagnosis of Zenker's diverticulum was based on clinical symptoms and the result of upper GI tract barium examination. In 75% of patients the diameter of diverticulum exceeded 2 cm. No patient died in the perioperative period. The main complications observed in the postoperative period were of pulmonary origin. In group I (excision) a leakage from the suture line occurred in 2 patients (12.5%). Time of follow-up ranged from 1 to 20 years (mean: 7 years). The comparison of both methods of treatment employed is in favour of diverticulopexy, being a safer and less complications-bearing method, although both of them give similar functional results.

[Esophageal resection for cancer--analysis of postoperative complications from personal materials]. / Resekcje przelyku z powodu raka--analiza powiklan pooperacyjnych w materiale wlasnym.

The aim of the present study was to analyse the rate of postoperative complications in patients after esophageal resection for cancer, as well as the dependence of its frequency from surgical tactics employed during the operation. Postoperative complications occurring in 38 patients who underwent esophagectomy and intrathoracic esophagogastric anastomosis (treated from 1978 to 1987) were compared with the same data of 74 patients (1988-1996) in whom the operation consisted of the total intrathoracic esophagectomy, cardia, lesser curvature of the stomach and large regional lymph nodes dissection. In these latter cases the esophagogastric anastomosis was performed in the neck. The most frequent postoperative complications in both groups were of cardiopulmonary origin. The anastomotic leak occurred less frequently in patients with cervical esophagogastric anastomosis. However, when occurred, healing was more likely by local drainage and conservative treatment. Anastomotic leaks after intrathoracic esophagogatric anastomoses were usually fatal. In these cases the only chance of patient's survival was an aggressive surgical treatment consisting of disconnection of alimentary tract: esophageal fistula in the neck and feeding jejunostomy.

[Orthotopic liver transplantation in clinical materials]. / Ortotopowe przeszczepienie watroby w materiale kliniki.

The authors present their own experience in orthotopic liver transplantation as a treatment of acute and chronic liver failure. 18 transplantations were performed in 16 patients. The indications for transplantation: acute liver failure-3 cases, chronic advanced disease of the liver-13 cases, graft failure requiring retransplantation-2 cases. All 3 patients with acute failure died after transplantation. Out of 13 patients after elective transplantations 11 remain alive, (in this number both retransplanted). The longest follow-up period is 2.5 years.

[Orthotopic liver transplantation using timely veno-venous bypass]. / Ortotopowy przeszczep watroby z zastosowaniem czasowego, pozaustrojowego by-passu zylno-zylnego.

The authors present their own experience in the use of veno-venous bypass during the anhepatic phase of orthotopic liver transplantation. The selected hemodynamic parameters (arterial pressure, central venous pressure, peripheral resistance) of the anhepatic phase as well as the effects of the graft reperfusion were analyzed in the group of 14 adult orthotopic liver allograft recipients transplanted in the Dept. of General Surgery & Liver Diseases from December 1994 to April 1997. In conclusion, the use of the veno-venous bypass allowed to avoid severe hemodynamic disturbances during the anhepatic phase and to minimize the complications of the reperfusion syndrome. The possibility of the relatively safe prolongation of the anhepatic phase is particularly important during the period of gaining experience by the surgeons and anesthesiologists.

On the basis of 101 pancreatoduodenectomies the authors present early postoperative complications. Cancer was surgical indication for pancreatoduodenectomy in 87 patients and inflammatory tumor of pancreatic head in 14 patients. Complications occurred in 37 cases. The most frequent complications were pancreatic fistula and disturbances of stomach emptying, in most cases treated conservatively. Mortality rate was 6.9%.

[Treatment of liver injuries in personal clinical material from 1990-1996]. / Leczenie obrazen watroby w materiale wlasnym Kliniki w latach 1990-1996.

From 1990 to 1996 two hundred and sixteen patients with abdominal trauma were treated in our Department. In 170 cases there were blunt, and in 46-penetrating injuries (stab and gunshot wounds). Injuries of the other regions of the body coexisted in 117 patients (multiple trauma). In 42 cases (19.4%) abdominal trauma caused injury to the liver. In this group blunt mechanism of trauma also dominated (71%). The victims were usually young men (90% of the group, mean age - 35.3 years). The most common cause of injury were traffic accidents (47.6%), penetrating injury being the second commonest cause (12 patients i.e. 29%). Four patients were treated conservatively, the remaining 38 required surgical intervention. Most frequently liver suture and peritoneal drainage were performed (20), followed by liver tissue resections (16) and liver packing (12). Other surgical procedures to treat coexisting injuries were performed in 24 patients. In 22 patients postoperative complications occurred: liver abscess in 6 cases, hemorrhage in 4, wound infection in 4, biliary fistula in 2, intrahepatic aneurysm in 2 and other complications in 8 patients. The mean time of hospitalisation were of 20 days (range: 0-64 days). Mean volume of blood transfused equaled 6.9 U. There were 16 deaths (38%), in all cases in multiple trauma victims. All patients with penetrating liver trauma survived.

[Analysis of morbidity risk in patients after liver resection]. / Analiza ryzyka powiklan u chorych po resekcjach watroby.

The authors present the retrospective analysis of the morbidity risk in patients undergoing hepatic resection for various indications. The most important complications, according to the literature, were: postoperative liver failure, massive pleural effusion, ascites resistant to pharmacological treatment, intraperitoneal hemorrhage or septic complications requiring relaparotomy. There was the correlation between the increased morbidity and preoperative risk factors like: diabetes mellitus, liver insufficiency with coagulopathy, and intraoperative blood loss, requiring massive transfusions.

[Complications after liver resection for benign lesions]. / Powiklania po resekcjach watroby z powodu lagodnych zmian ogniskowych.

[Reconstructive surgery in iatrogenic bile duct injuries]. / Operacje naprawcze w jatrogennym uszkodzeniu dróg zólciowych.

The paper presents the results of surgical treatment performed in 54 patients with iatrogenic injury of biliary tract. All cases of injury were made during open and laparoscopic cholecystectomy. We concluded that Roux-en-Y hepatico-jejunostomy should be recommended. There were no deaths after surgery. This technic was successful therapeutic management more than 95% of cases.

[Surgical treatment of biliary tract neoplasms]. / Chirurgiczne leczenie guzów dróg zólciowych.

The authors present their own experiences concerning the treatment of the 34 patients with the benign and malignant tumors of the biliary tract. In the group of patients with malignant tumors, the type and extent of the surgery were dictated by the stage of the disease. Patients with benign tumors were subjected to resection of the region of bile duct bifurcation with Roux-Y hepaticojejunostomy.

[Selected aspects of nutritional support in patients after liver transplantation]. / Wybrane aspekty leczenia zywieniowego u chorych po przeszczepieniu watroby.

The majority of liver transplanted patients are severely malnourished that increases the incidence of postoperative morbidity and mortality. The authors analysed the effects of nutritional support-total parenteral nutrition-in 11 adult orthotopic liver allograft recipients (9 women, 2 men) transplanted for chronic or acute liver failure in 1994-1997. 4.3-9.75 g of N/24h, 1200-1700 kcal in 1750-2750 ml, from 2-5th postoperative day was administered via central vein in all-in-one system for 4-46 days. Neither metabolic nor septic complications related to the nutrition were observed. The function of the transplanted liver was not impaired by the nutrition. One patient died in course of hepatic coma, 10 patients are alive and in good general condition (1-29 months). In conclusion, the total parenteral nutrition is safe, beneficial and thus recommended routine therapy in the treatment of the liver transplanted malnourished patients.
